Appiiatiqn'iea February a5, i924. serial No. 695,113.

My said invention relates to an automatic cash re-register and it is anob]ect of the same to provide means in the main office of a store crother place where cash registers are usedl for indicating automaticallythe number of sales and the amount thereof.

Referring to the accompanying drawings,

which are made a part hereof and on which y similar reference charactersindicate similar parts, Y

Figure 1 is a diagrammatic view of a system embodying my invention,

Figure 2, a fragmentary detail of a single unit on a larger scale, and

Figure 3, a side elevation of in Figure 2;

In the drawings reference characters indicate individual members of aseries of cash registers located in various parts of a store either onthe same floor or on different floors, these cash registers beingconnected by electrical connections 11 to re-registers 12 in the mainoiiiee arranged in a set or series in any convenient 'way so as to maketheir information quickly available.

Each of the registers 10 as usual contains a series of totalizer wheels13 for rendering parts shown the total after each operation of themachine. According to my invention I pro` vide a corresponding series ofWheels 14: geared to the respective wheels 13, each of the wheels 14Ebeing provided at one side with a cam wheel or cam portion 15 having itssurface provided with a plurality of notches and forming teeth or as aseries of similar equally spaced high and low parts as illustrated inFigure 3. A follower or escapement- 16 has a pair of spaced extremitiesor points 17 and 18 joined by a curved surface, saidV teethV contactingor cooperating with the curves or angular sides of the cam and followingclosely along opposite sides of adjoining teeth. A conductor 19 isconnected to the pivot 2O of the follower and another conductor 21 isconnected to a contact 22 adapted to engage the tail 23 of the follower.The contact 22 is supported on a pivoted arm 24: which may bespringpressed toward the tail of the follower if desired.

The conductors 19 and 21 are connected through a battery to a solenoid25 having an armature 26 normally held in raised position by a spring27. The armature is provided at its lower end with a pivoted pawl 28iinpelled by a spring 29 in a direction to engage and operate a ratchet30.

The ratchet 30 (Fig. 3) is one of a series shown in Figure 2 each ofwhich has integral therewith ay digit wheel 31 the whole seriesconstituting a totalizer similar to that on the corresponding cashregister 10. The disks 31 are visible through a window 32 in usualfashion as at 12 iii Fig. 1 and the -ratchets 30 are held againstreverse movement by deteiit pawls 33 held in engaging position bysprings 34.

In the operation of the device each of the re-registers 12 in the mainoffice will be actuated at each operation of the individual registers10, the movement of a totalizer wheel 13 causing the rotation of thepinion 14 meshing with the teeth of the pinion secured to'or rigid withthe wheel 13 and so turning the cani 15 to oscillate the follower 16thereby closing the circuit at 22, 23 each time that a high place on thecani passes. When this takes place the solenoid 25 is energized so thatthe corresponding armature is pulled downward to turn the ratchet i 30thereby the digit wheel 31 fixed thereto will be turned to offer thesaine indication as on the correspondingwheel of the individual cashregister.

It will be obvious to those skilled in the art that numerous additionsmay be ymade to what is shown in the drawings and described in thespecification as' well as modi* ications of the devices therein setforth all without departing from the spirit of the invention. Forexample it will be entirely possible to provide devices for showing in`the main office the total number of sales or the sales by individualsales persons as is customary'in large stores thereby making availablein the main office, without delay or trouble, the relative activity ofvarious Vsales persons and otherwise affording in formation of value.Instead of totalizer wheels Iv may use indicating means of other formsand generally the form and arrange ment of parts may bevaried accordingte need or preference. For the reasons above set forth I do not limitmyself to the precise embodiment of the invention shown and describedbut only as indicated in the appended claim.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent is:

The combination of prima-ry registers Vhaving digit wheels,re-registering means in cluding digit wheels, independent electriccircuits between pairs of wheels in the respective sets, means foropening and closing; each circuit including a cam-Wheel driven by thefirst-named digit Wheel said cam- Wheel having a series of teeth, enescapement contacting simultaneously with sides of two teeth, e terminal0n the escepement, and means operated'by the eleetrle circuit to drivethe re-registerng Wheel of the pair in synehronism with the other,substantially as set forth.

In Witness whereof, I have hereunto set my hand and seal at Bangor,Maine, this 23rd dey of February, A. D. nineteen hundred andtwenty-four.
